Description

LYN-1604 hydrochloride is a potent UNC-51-like kinase 1 (ULK1) activator (EC50=18.94 nM) for the research of triple negative breast cancer (TNBC)[1].

IC50 & Target[1]

ULK1

18.94 nM (EC50)

In Vitro

LYN-1604 is a potential ULK1 agonist (enzymatic activity=195.7% at 100 nM and IC50=1.66 μM against MDA-MB-231 cells) [1].
LYN-1604 binds to wild-type ULK1 with a binding affinity in the nanomole range (KD=291.4 nM) [1].
LYN-1604 (0.5, 1.0 and 2.0 μM) induces cell death via the ULK complex in MDA-MB-231 cells[1].
LYN-1604 (0.5-2 μM, 24 hours) induces remarkable up-regulation of Beclin-1 and degradation of p62, as well as transformation of LC3-I to LC3-II in MDA-MB-231 cells[1].
LYN-1604 induces ATG5-dependent autophagy via the ULK complex[1].
LYN-1604 can also increase cleavage of caspase3 and induce apoptosis[1].

Incubation Time:
Result: Induced cell death. Autophagy ratio was increased in a dose-dependent manner.

Western Blot Analysis[1]

Cell Line: MDA-MB-231 cells
Concentration: 0, 0.5, 1, and 2 μM
Incubation Time: 24 hours
Result: Induced remarkable up-regulation of Beclin-1 and degradation of p62, as well as transformation of LC3-I to LC3-II.
In Vivo

LYN-1604 (low dose, 25 mg/kg; median dose, 50 mg/kg; high dose, 100 mg/kg; intragastric administration once a day for 14 days) inhibits the growth of xenograft TNBC by targeting ULK1-modulated cell death[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 24 female nude mice (BALB/c, 6-8 weeks, 20-22 g)[1]
Dosage: Low dose, 25 mg/kg; median dose, 50 mg/kg; high dose, 100 mg/kg
Administration: Intragastric administration; once a day for 14 days
Result: Significantly inhibited the growth of xenograft MDA-MB-231 cells. The body weights of mice were stable. By the end of the experiment, the liver and spleen weight indexes of mice were slightly increased in parts of the groups, while the kidney weight index was not affected in all dose groups.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.03 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (4.03 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
